In the games

Inside Driftveil Gym, there are a number of elevators that are in the mine shaft layout which must be navigated up and down and girders which need to be crossed to reach the central elevator, which will take the player down to Clay at the bottom of the mine shaft. There are several Trainers on the way down.

One of the Trainers in the Gym mentions that the depth of the Driftveil Gym helps to remind Clay that he once started at the bottom with nothing.

In Black 2 and White 2, the Gym no longer features the elevator puzzle, but is instead replaced by a conveyor belt puzzle that takes the player to landing platforms. Each time the player lands on a new platform, it lights up. Occasionally there will be viewing platforms, which allows the player to see several platforms from above.
